Right ventricular performance in patients with heart failure with mildly reduced ejection fraction: the forgotten ventricle.
Article in The international journal of cardiovascular imaging, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Right ventricular (RV) function is a major determinant of prognosis and adverse outcomes in patients with heart failure (HF). It is largely unknown if HF with mildly reduced ejection fraction (HFmrEF) patients have some special characteristics in RV function (RVF) that may distinguish them from HF with reduced or preserved ejection fraction (HFrEF or HFpEF) patients. Standard echocardiography was performed to estimate RVF [tricuspid annular systolic velocity (TDSV), plane systolic excursion (TAPSE), TAPSE to pulmonary artery systolic pressure (TAPSE/PASP) and RV myocardial performance index (MPI-TEI index)] in a cross-sectional study. In 306 participants, the RV systolic function evaluated with TAPSE and TDSV was impaired in 39.1 and 24.2%, respectively. TAPSE, TAPSE/PASP and TDSV were lower in HFmrEF compared with HFpEF and higher compared with HFrEF (p < 0.001 for among-groups comparison). RV diastolic dysfunction varied between 12.6 and 43.8% depending on the echocardiographic parameter. Diastolic RVF determined by tricuspid inflow E/A wave ratio (Et/At) was impaired in less patients with HFmrEF compared with those with HFpEF or HFrEF (25.9% vs 48.4% vs 56.3%; p = 0.030, respectively). RV diastolic dysfunction by et'/at' (tissue Doppler tricuspid valve annulus e' and a' waves) was impaired in less patients with HFmrEF compared with HFrEF (11.8% vs 33.3%; p = 0.019). A multivariate regression analysis revealed a significant association between RV and LV systolic dysfunction. The present study shows a high prevalence of RV dysfunction in HFmrEF patients. Study findings provides some new insights on RV and LV systolic dysfunction coupling whereas RV diastolic dysfunction was not dependent on LV systolic dysfunction.
